For some reason I was under the misgiving that every newbie used to post an idea for carbon filter underwear. Sadly, those contributors were too limited in their postulating. Where the real future sits is in carbon filter seat cushions and covers.
Strictly because I picked the wrong category, I also believe that some cushions should blow up delicious aromas, like a silent whoopie, as a preemptive measure.-- 4and20, Mar 15 2021random, halfbakery
